Rehabilitating mangroves with a sediment nourishment: An initial assessment using a schematised model

Mangroves are productive ecosystems. Degradation of mangroves has been observed since the 1970s, due to a variety of reasons. Successful rehabilitation focuses on restoring conditions suitable for mangroves. Sediment availability has been shown to positively impact mangrove growth. Therefore, it can likely play a role in mangrove rehabilitation....

Trench Siltation near the ETM of a Well-mixed Estuary

To exploit its socio-economic functions, engineering measures are regularly applied in estuaries. Estuaries are, however, known to be very complex systems. Stemming from this complexity is the generation of a so-called estuarine turbidity maximum (ETM), which poses great siltation problems to the engineering measures. An engineering measure,...

Coastal dune behavior and the role of sediment supply in the aeolian system

This thesis explores the nature of coastal dune behavior and the role of sediment supply in the aeolian system. The first part of the thesis conducts a data analysis based on the Dutch JARKUS dataset, which provides yearly measured profiles along the Dutch coast. A series of parameters derived from the profile measurements have been used to...

Sequence stratigraphic analysis of Eridanos deltaic shallow gas-bearing deposits in North Sea: An insight into the shallow Dutch subsurface

Growing interest has been expressed the last decades regarding the Late Cenozoic, gas-bearing sediments of Southern North Sea Basin. Comprising the shallow subsurface of the Dutch offshore sector, these sediments have<br/>been deposited by Eridanos fluvio-deltaic system, draining the Fennoscandian and Baltic shield through the present Baltic Sea...

Aeolian Sediment Transport at the Hondsbossche Dunes

In 2014-2015 the coastal stretch between Petten and Camperduin was strengthened by using 35 million m3 of sand. At the seaward side of the Hondbossche & Pettermer sea defence a beach and dune system was built which is called the ‘Hondsbossche Dunes’. The old sea dike has disappeared behind the new dunes and is no longer an active part of the...

Analysis of the impact of sedimentological heterogeneity and fractures on fluid flow properties in a deltaic reservoir setting using numerical models

Process-based numerical simulations in river delta modelling have demonstrated the importance of hydraulic and sedimentary forcing mechanisms on delta morphodynamics. Insights of these simulations on deltaic systems have a high potential to improve reservoir predictions in the industry. However, detailed morphological studies are typically...

Analysis of the effects of process variations on delta morphology and stratigraphy in Delft3D computational models

Deltaic reservoirs are of great significance in both exploration and production of oil & gas and they have aroused increasing interest during the recent years. Coastal engineering deals with sediment transport on a millisecond and micron scale, while geology deals with sequence stratigraphy on a millenary and 10-100 km scale. However, relatively...

The influence of dredging activities on the morphological development of the Columbia River mouth

This is a numerical modelling study on the impact of dredging and disposal activities on the long-term morphological development of the Columbia River mouth (MCR). Dredging activities removed 120 Mm3 of sand from the MCR during the studied interval between 1958 and 1999. Only one-third of this volume was disposed in the active littoral zone....

Modelleren van een kunstmatige rivier ter plaatse van de Hondsbossche en Pettemer zeewering

Het onderwerp van dit afstudeerproject is ontstaan naar aanleiding van een prijsvraag van de gemeente Zijpe. Ter gelegenheid van het 400-jarig bestaan van de Zijpe en Hazepolder werd een prijsvraag uitgeschreven met als onderwerp: "kijk op de kust". Door de TU-Delft, in samenwerking met Alkyon, werd aan de prijsvraag meegedaan. Hun "kijk op de...
